SEEDER'.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed August 5, 1905. Serial No. 272,873-

To all whom it may concern.-

Be it known that I, SAMUEL K. DENNIS, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Seeders, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to seeders having revolving grain-distributers that are given motion by means of gear members connected with the ground-wheels of the machine; and

it consists in improved means for causing. the

engagement or disengagement of the gear members with the distributing devices, the object being to provide a mechanism that will be easily manipulated and conveniently located for the desired purpose. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a rear View of a seeder having my invention forming a part thereof. Fig. 2 is an end view of the machine, showing the driving-gear disconnected from the distributer-gear; and Fig. 3 represents the same parts and having the driving-gear connected with the distributer-gear.

Similar numerals refer to similar parts throughout the several views.

"*4 represents the seed-hopper mounted upon longitudinally-arranged frame members 5 and 6 and having stub-axles? secured to opposite ends thereof, upon which are journaled the ground-wheels 8, one only being shown in Fig. l.

9 is a spur-gear arranged concentric with the stub-axle and deriving motion from the ground-wheel by means of any of the common forms of pawl-and-ratchet mechanism.

10 is a spur-gear secured to the distributershaft 11 and deriving motion from the spurgear 9 by means of the intermediate gear 12, mounted upon an arm 13, adapted to swing about the axis of the spur-gear 9, and having the outwardly and downwardly curved portion 14 provided with a slotted opening 15, adapted to receive the crank-arm portion 16 of one end of a rock-shaft 17, suitably mounted upon the frame of the machine, and having secured at its opposite end an adjusting-lever 18, having a common form of sliding detent engaging with a toothed sector 19, mounted upon the frame concentric with the axis of the distributer-shaft.

Each end of the machine is provided with like gear members and the two rock-shafts are independently operative and have their inner ends, upon which are mounted the adjustinglevers in juxtaposition at the center of the machine-frame, where they are convenient to the hand of' the operator. If the adjustinglevers be thrown inward toward the seed-hop per, the crank-arms at the outer ends of the rock-shafts operate to swing the arms 13 upward about their pivotal axes and to thereby disengage the intermediate gears 12 from the gears 10, mounted upon the distributer-shaft, and when moved in an opposite direction they operate to cause engagement of said gears, the slotted openings at the end of the arms 13 permitting the crank-arms to slide therein in a manner to prevent binding of the same.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a seeder, the combination of a hopper, ground-wheels suitably journaled at opposite ends thereof, a distributer-shaft suitably journaled below the bottom of said hopper, motion-transmitting means connected with said distributer shaft and ground wheels, and means for disengaging said connection comprising a gear member mounted upon a swinging arm, a rocking crank-shaft arranged longitudinally relative to the hopper and having its crank portion engaging with said arm, an adjusting-lever secured to said shaft at or near the center of the hopper, and means for securing said lever in any desired position.

2. In aseeder, the combination of a hopper and a frame, ground-wheels suitably journaled at opposite ends thereof, a distributer-shaft suitably journaled below the bottom of said hopper, motion-transmitting means connected with said distributer shaft and ground-wheels comprising spur gears arranged coaxially with the ground-wheels and adapted to be driven thereby, spur-gears secured to opposite ends of said distributer-shaft, arms mounted to swing about the axes of the groundwheels, intermediate pinions journaled upon said arms and adapted to mesh with said spurgears, and means for swinging said arms about their axes in a manner to move said intermediate pinions out of mesh with the spur-gears on said distributer-shaft, comprising r0ckshafts mounted upon said frame and arranged longitudinally thereof, crank-arms at the outer ends of said shafts and engaging with said swinging arms, the inner ends of said shafts meeting near the center of the hopper and provided with adjusting-levers secured thereto.

3. In a seeder, the combination of a hopper and aframe, ground-wheels suitably journaled at opposite ends thereof, a distributer-shaft suitably journaled below the bottom of said hopper, motion-transmitting means connected with said distributer-sha'ft and ground-wheels, comprising spur gears arranged ooaxially with the ground-wheels and adapted to be driven thereby, spur-gears secured to opposite ends of said distributer-shaft, armsmounted to swing about the axes of the groundwheels, intermediate pinions journaled upon said arms and adapted to mesh with said spurgears, said arms being curved outward and downward from the intermediate pinions and SAMUEL K.
